Model fits
At-a-glance
Figure 1: Time series of spawning biomass with scaled spawn indices (top), recruitments (second row), natural mortality (third row), and harvest rates (bottom row) for substocks of SOGHerring. Stocks are, from left to right,SOG.
Fits to data
Figure 2: Probability of detection of a spawning event, with respect to spawning stock biomass. Lines show the modeled probability and the points indicate whether a spawn was detected, with 0 for no spawn detected, and 1 for a positive index.
Figure 3: Average model fits to age data. Stocks are left to right, and gears are top to bottom.
Figure 4: Model fits to age data, averaged over stock and time. Gears are top to bottom.

Recruitment
Figure 5: Age-1 recruitments for all stocks. Equilibrium unfished recruitment \(R_0\) is indicated by the horizontal dashed line. Second row shows recruitment residuals on the log scale, with the average of estimated residuals shown by the horizontal red dashed line.

Natural Mortality

Figure 8: densityDependent M
Figure 9: Total natural mortality at age
Figure 10: Total mortality at age
Selectivity and Catch
Figure 11: Catch in biomass units for each stock (rows). Stacked bars show the total yearly catch for each commercial fleet.
Figure 12: Catch in biomass units for each stock (rows). Stacked bars show the total yearly catch for each commercial fleet.
Figure 13: Selectivity-at-age for each fleet (rows). Aggregate stock average selectivity curves are shown as thick grey lines, while sub-stock specific estimates are shown as dashed thin coloured lines.
